Modeling Avalanches: "We're still in the kitchen."
Christophe Ancey warns against relying blindly on the output of computational avalanche models to evaluate the safety of alpine areas. Recent events prove him right. Christophe Ancey, head of EPFL's Laboratory for Environmental Hydraulics, is an expert in modeling avalanches and other environmental flows.

«Physics Fights» an der Empa
Wieso hüpft ein Golfball wieder aus dem Loch? über solche und ähnliche Probleme stritten sich physikbegeisterte Schülerinnen und Schüler am «Swiss Young Physicists‘ Tournament» Ende März an der Empa.

New TIP paper accepted
Scale-invariant features and novel descriptors for omnidirectional images accepted for publications in IEEE Transactions on Image Processing. Scale Invariant Features and Polar Descriptors in Omnidirectional Images Zafer Arican and Pascal Frossard We propose a method to compute scale invariant features in omnidirectional images.

Die Anden wachsen dem Niederschlag entgegen
Die Anden formten sich in den letzten 10 Millionen Jahren asymmetrisch: Ungleichmässige Niederschlagsmengen führten zu einer Verformung der Erdkruste vor allem auf der Ostseite der südamerikanischen Gebirgskette, wie ein Berner Geologe herausfand. Gebirge stehen in einer dynamischen Wechselwirkung zwischen Hebung und Abtragung.

Innovative method to measure action potentials between cells.
Parameter extraction and classification of three cortical neuron types reveals two distinct adaptation mechanisms. Cortical information processing originates from the exchange of action potentials between many cell types. In order to capture the essence of these interactions it is of critical importance to build mathematical models that reflect the characteristic features of spike generation in individual neurons.

New book on Optimal Control Theory
Thomas Weber published a new book at MIT Press, which gives a rigorous introduction to optimal control theory, with an emphasis on applications in economics. Content This book bridges optimal control theory and economics, discussing ordinary differential equations, optimal control, game theory, and mechanism design in one volume.
